2. (39) Two
masses are connected by a cable that is
wrapped around a pulley ofmoment of
inertia Iandradius R = 1.0 m.The acceleration of the blocks has magnitude a = 0.020 m/s2. No friction.

(a) (5) What isT2 ?

(b ) (5) What is T1 ?
(c ) (11) What is I?
(d)(5) If the pulley is in the shape of
a solid disk, then what is the mass M of the pulley?
(e)(3) Assume the system starts from
rest. What is the speed v of the blocks after 5.0 seconds?

(f)(6)What is the magnitude L of the angular momentum of the
pulley after 5.0 seconds?

(g) (4)What is
the direction, in or out of
the page,of the angular
momentum of the pulley after 5.0 seconds of motion? Assume the
axis of rotation is perpendicular to the page.

(30) A
beam is attached to a wall, and at
the other end is held in place by a cable of tension T. Check out the
diagram. The beam has mass 50.0 kg. As you can see, the beam makes an angle of 60 degrees
with the horizontal.

(a)(16)What is
the tension T ?

(b)(6) What is
the horizontalcomponent of force Fh
exerted on the beam by the wall ?

(c)(8) What is
the verticalcomponent of force Fv
exerted on the beam by the wall ?
